We compared the European honeybee races Apis mellifera armeniaca, A.m. caucasica, A.m. cypria, and A.m. syriaca. These subspecies are endemic to very different habitats. Additionally, they are exposed to very different levels of predation. A.m. caucasica exists where honeybee predators typically are rare, while the remaining subspecies have ranges that coincide with areas where honeybee predators are abundant. Foraging decisions of workers visiting artificial flower patches containing blue, white, and yellow flowers were recorded. We tested whether foragers responded to differences in rewarding flower frequency among flower color morphs. Division of labor occurred among foragers of each race; some bees frequented yellow flowers while other bees from the same hive visited blue and white flowers. A.m. caucasica foragers ignored differences in reward frequency among flower colors. Even bees that frequented blue and white flowers did not base flower choice on reward frequency differences between just these two color morphs. In contrast, A.m. armeniaca, A.m. cypria, and A.m. syriaca, however, did respond to differences in reward frequencies, tending to avoid the less frequently rewarding flower color morph. A.m. armeniaca forager division of labor (foragers committed to yellow or to blue and white flowers) was dominant to energy maximization. The reverse was true for A.m. cypria.
